        Africa 2.0

        Inside a continent’s communications revolution

        by Russell Southwood

        Africa wired up provides an important history of how two technologies - mobile calling and internet - were made available to millions of Sub-Saharan Africans and the impact they have had on their lives. The book deals with the political challenges of liberalization and privatization that needed to be in place to get these technologies built. It analyses how the mobile phone fundamentally changed communications in Sub-Saharan Africa and the ways Africans have made these technologies part of their lives. It examines critically the technologies' impact on development practices and the key role development actors played in accelerating things like regulatory reform, fibre roll-out and mobile money. The book considers how corruption in the industry is a prism through which patronage relationships in Government can be understood. The arrival of a start-up ecosystem has the potential to break these relationships and offer a new wave of investment opportunities. The author seeks to go beyond the hype to make a provisional assessment of the kinds of changes that have happened over three decades. It examines how and why these technologies became transformative and seem to have opened out a very different future for Sub-Saharan Africa.

        Voice over IP

        An Introduction to Techniques with SIP

        by Thomas Wübbe

        Since the switch-off of classic telephony technology in 2019, the Session Initiation Protocol (SIP) dominates providers' telephony solutions. This book gives an introduction to this technology. It shows principles as well as the common architecture of Voice over IP with SIP. In addition to differences and changes to the "old" telephone technology, step-by-step methods and requirements for Voice over IP are discussed.Many protocol examples show how SIP works. They help troubleshooting when something does not work. A special practical chapter shows how to do analyses via Wireshark and explains logging in detail. These topics are included: Fundamentals of packet switching and standardization, Internet Protocol (IP) VoIP principle, Architecture of SIP SIP signaling Session Description Protocol (SDP) VoIP and NAT Quality of Service (QoS) Introduction to packet analysis with Wireshark, and Practical exercises.

        Hyperspectral Remote Sensing and Spectral Signature Applications

        by S. Rajendran, S.Aravindran, T.Jeyavel Rajakumar, R. Sivakumar & K.R. Murali Mohan

        Hyperspectral imaging is an emerging modern technique in modern remote sensing that expands and removes capability of multispectral image analysis. It takes advantage of hundreds of continuous spectral channels to uncover materials that usually cannot be resolved by multispectral sensoThis book is a collection of research papers of Indian scientist working in the field of hyperspectral remote sensing and spectral signature applications. This has been organized in a way that all the s are logically connected and can be referred back and the forth one another for more details. The title of hyperspectral remote sensing and spectral signature applications is use to reflect its focus on spectral techniques, i.e. non-literal techniques that are especially designed and developed for hyperspectral imagery rather than multispectral imagery.

        Wired for Sound

        Engineering and Technologies in Sonic Cultures

        by Paul D. Greene

        Wired for Sound is the first anthology to address the role of sound engineering technologies in the shaping of contemporary global music. Wired sound is at the basis of digital audio editing, multi-track recording, and other studio practices that have powerfully impacted the world's music. Distinctions between musicians and engineers increasingly blur, making it possible for people around the globe to imagine new sounds and construct new musical aesthetics.;This collection of 11 essays employs primarily ethnographical, but also historical and psychological, approaches to examine a range of new, technology-intensive musics and musical practices such as: fusions of Indian film-song rhythms, heavy metal, and gamelan in Jakarta; urban Nepali pop which juxtaposes heavy metal, Tibetan Buddhist ritual chant, rap, and Himalayan folksongs; collaborations between Australian aboriginals and sound engineers; the production of "heaviness" in heavy metal music; and the production of the "Austin sound." This anthology is must reading for anyone interested in the global character of contemporary music technology.
